To all whom it may concern:

Be it known that I, CHARLES AJJAYNES, a"

citizen of the United States, residing at East Orange, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Insulating-Joints, of which the following is a full,clear, :andexact specification.

- ether as a firm and unitary structure.

My invention relates to meansfor insulating sections of pipe from eachother, and the,

same has for its object more particularly to provide a simple,eificie-nt and reliable :joint which may be applied to gas pipes inorder to insulate the fixtures attached thereto from said pipes.

' Further, said invention has for its object to provide a joint for thepurposes specified, in which its several parts are secured tosaidinvention, and Fig. 2 is 'a-oentral-vertical -.section of the same.

in said drawings 1 0 -de nates 'a sceket provided upon its innersuacewith screw threads 11 and atits lower end said socket "is provided witha reduced option" 12 ifiorming a support having a centre opening 13extending therethrough and connecting With-the interior-of said socket.Atthe-junctionof .the base of said socket with the upper end of thered-uced'portion 12 is provided a'laterally projecting flange-14-havmg1its underside partly beveled at 15; l j 16 and 17 denoteannular sections of insu- Y posed upon thered-uced end portion 12 ofthe.

lating material, such as mica, which are dissocket and clamped inposition thereon adj acent to their inne ed es by means 01' a metalwasher 18 which is he din position by the innerend of the reducedportion '12 which is turned over-or riveted against the lower suriace ofsaid metal washer 18.

1 9 denotes asleeve provided at its upper ."Blld with anfiinwardlyextending tapering fiange 2Q hay-in its upper and lower surfaces toproduce astral-z p l inner edge which is adapted for securement to thesocketl 1 intermediate the outer edges of the-insulating sections lfiand17; the inmay fit the sleeve 19.

sulatingsectiofl 17 being of smaller diameter 0' than the section 16 inorder that-the same 21 denotes a second socket member which i isprovided upon its inner-surface with screw threads 22 and above saidscrew threads with a centrally disposed openin 23. l

24 denotes a laterally pro ecting flange arranged at the inner .or upperend 61'' the so ket member 21, which flange is substane tialjyco-extensive in diameter with the interior diameter of the sleeve 19.

25 denotes a disk of insulating -material provided with a centrallydisposed opening 26 i1 line with the opening 23 in the socke 1 member 21and the opening '13 in the reduce portion12 lot the socket 10, and abovesaid insulating disk 25 is disposed .a second dis-k or la er ofinsulating material 27 which tog-e er serve to insulate the socketmember 21 audits flange 24 from the socket member 10 and its reduced endportion 12. The

socket member 21 issecured firmly within the sleeve 19 by a'rim 27 atthe lower end of said sleeve 19 which is bent inwardly and bears againstthe outer or lower surface of the ffiange 24, and thereby. holds the twosections firmly and permanently united.

It will be noted that in .aotualuse the joint may be applied, forexample, at the socket portion 10 to a gas pipe, and at the socketportion 21 to the upper end of a combined gas-and electric-"fixture, andby the arrangement and construction of the parts shown A and describedsaid fixture wilLbeabsolutely insulated from the pipes for conductingthe gas to said fixture. Eurther, it is to be noted that when the jointis used in connection with an electric fixture merely the reduced end 12of the socket- 10 may be made solid, 1

but when the joint is to be used in connection with acomblned andelect-r10 h'xture the said reduced end 12 must beprovided with anopening asshown, for the passage of the gas.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. A joint of the character-described, comprising asocket member,insulating members separated at theirrouter edges andniveted 'togatherat theircentmal' portions andto said =soeket'member,asleeveimgagingsggidsocket member intermediate the separated edges of said sleeve, andinsulating material disposed said insulating members, and a socketmember secured to said sleeve and insulated from the socket memberfirst-named, substantially as specified. j

2. A joint of the character described comprising a socket member, asupport centrally arranged thereon, insulating means secured to saidsupport with their outer edges se arated, a sleeve secured to saidsocket m'em er and engaging the insulating meansthereon intermediate theseparated edges thereof, and

a socket member secured to said sleeve and insulated from the socketmember firstnamed, substantially as specified 3. A joint of thecharacter described comprising a socket member, a reducedend integraltherewith and extending therefrom, a

plurality of insulating members secured to said reduced end, a sleevesecured atone end to said socket member intermediate the insulatingmembers thereon, and a socket 'member secured to the other end of saidsleeve, substantially as specified,

' 4. A joint of the character described, comprising a socket member, areduced end integral therewith and extending therefrom, a plurality ofinsulating members secured on said reduced end, a sleeve secured at oneend to said socket member intermediate the insulating members thereon, asocket member secured to the other end of said sleeve, and insulatingmeans interposed between said socket member's, substantially asspecified.

5. A joint of the character described c omprising a socket member, atubular section extending therefrom, a plurality of insulat ing-sectionssurrounding said tubular section, a sleeve secured to said socket memberintermediate the insulating sections thereon, a secondsocket membersecured within said sleeve, and an insulating section interposed betweensaid-socket members, substantially as specified.

' 6. A joint of theenaracter described comprising a socket member, atubular section extending therefrom, insulating washers disposed uponsaid tubular section, a sleeve having a flange at one end adapted forsecurement to said socket member intermediate said insulating washers, asecond socket 'member disposed Within the other end of said sleeve, andinsulating material arranged in said sleeve intermediate said tubularsection and the socket member lastnamcd, substantially as specified.
